Research On Technology Of Remote Monitoring And Control System Based On Internet

With the development of the network technical, internet technique has already permeated to each field of the daily life and the industry production .It made the remote monitoring and control of the industry automation production possible. Through the remote monitoring and control technique, the technical personnel needn't to attend personally or to be in bad environment. They can work at other places. That is one of the problems that people in the manufacturing industry and many other professions are always expecting the solutions. Remote monitoring and control technology includes the network technology, computer technology and control technology. It uses the network equipments, providing a new control method for inner factory or over area's monitoring and control.In this paper "Research on Technologies of Remote Monitoring and Control System Based on Internet", firstly research on the function, nowadays condition and the trend of the remote monitoring and control system. And then discuss on the B/S mode, TCP/IP protocol and UDP, TCP protocol and server programming language, Java, Java Applet's application in the system. Detailed discuss the multi-thread technology effect on the system's real-time performance and the Java language's support for multi-thread. Moreover, discuss the security performance of system, and the Java's security mode. In the end, summarise the paper and put forward the expection.
